Progressive Cavity Pump Rotor

We can design and process rotors in different geometric shapes to meet specific customer requirements. The metal materials used can also be treated for surface hardening or vacuum heating, with the hardness of the metal after treatment reaching HRC60-65°. The surface can also be sprayed with a tungsten carbide or chromium carbide in specific industries to give the surface a hardness of HRC68° in order to improve its wear resistance.

Introduction of common material of rotor
Material Corrosion resistance Abrasion resistance Chlorine resistant Cl- concentration(ppm) Suitable Application
Carbon steel general general poor For abrasive but noncorrosive fluid, cannot be used for food
Carbon steel (harden treatment) general excellent poor For non-corrosive but highly abrasive fluid
SS420 (harden treatment) general good poor For slightly corrosive and abrasive fluid
SS304 good general < 100 Can be used in the food industry and for non-corrosive acidic fluid
SS304 (harden treatment) good good < 100 For corrosive and abrasive fluid, cannot be used for food
SS316 good general 100~2000 Can be used in the food industry and for non-abrasive acid fluid
SS316 (harden treatment) excellent excellent 100~2000 For corrosive and abrasive fluid, cannot be used for food
Duplex SS excellent excellent 1000~40000 For corrosive fluid with high content of Cl ion but non-abrasive acid fluid
Duplex SS (harden treatment) excellent excellent 1000~40000 For corrosive fluid with high content of Cl ion and abrasive acid fluid

Note: the materials used in the rotor detailed above can be combined based on specific customer requirements, the particularity of the medium or actual work conditions. Please contact us for more detail.
